UltraBOOST X

UltraBOOST X

Give your last-best run some serious competition in these women's shoes built with ultra-cushioned boost. Designed to respond to the way your foot moves through each stride, the shoes feature a floating arch and an adidas Primeknit upper that hugs your foot throughout the gait cycle. Boost delivers maximum energy return, and a stretchy outsole flexes to adapt to the way your foot strikes the ground. Runs true to size.
